Red Snapper Lutjanus campechanus, is an important commercial and recreational fish species and there has been much interest in maintaining its status among a variety of scientific, social and economic levels. Stocks are influenced by varying environmental conditions, changing fishing effort and efficiency, anthropogenic effects, inter- and intraspecific interactions, bycatch from other fisheries, and habitat alterations. Red Snapper Biology in a Changing World explores these changing factors and their potential effects on Red Snapper in the Eastern Atlantic region including the Gulf of Mexico and Southeastern U.S. The book will provide a better understanding of Red Snapper population fluctuations that will subsequently allow for better management decisions and more informed user groups in their efforts to maintain a sustainable fishery. It explores the responses Red Snapper have made, and are making, relative to their life history attributes such as early life history and adult ecology, especially attributes associated with population distribution and abundance, movement patterns, fish health issues and management success. A compendium of many papers presented at the 147th annual meeting of the American Fisheries Society in Tampa, Florida, this volume also includes additional research completed as a result of the symposium. It will be essential reading for fisheries scientists and managers, ichthyologists, resource and environmental managers, and policymakers who are involved with coastal fisheries.

Structure in the Sea: The Science, Technology and Effects of Purpose-Built Reefs and Related Surfaces provides a review of the history, development, status and emerging trends in research, technology and applications of artificial reef habitats and sea floor structures. The book helps readers understand, utilize and add to the research of modern reef deployment efforts, presenting a guide to equip stakeholders requiring technical foundations and best practices. Topics include materials, designs and construction methods, along with the ecology of these structures, including key aspects of the life history of plants and animals associated with artificial reefs. Rigorous research addressing ecological, economic and engineering questions, coupled with the innovative deployment of structures worldwide by diverse stakeholders, have created a synergy that makes the book a valuable synthesis and analysis for this growing subject. Thus, its broad audience includes marine (coastal and ocean) environmental sciences, including aquatic ecologists, those working in ocean sustainability and conservation, benthic habitat and coral reef restoration practitioners, and more. - Presents a new perspective on how we might save natural wonders under threat - Provides a representation of reefs, showing the economic and humanitarian value of these natural ecosystems - Unlocks potentials for solutions for conservation by including global case studies

"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."

Among the most important reasons that artificial reefs have been created are the protection of the seabed with macroalgae, the possibility of improving fishing, and meeting the expectations and demands of tourists. Coastal managers have realized that it is important that artificial reefs are useful to people, especially local communities, and that it is therefore important that they are promoted by government entities for various professional and leisure activity use. Coastal managers must take this into consideration when reefs are designed. They must also define the ecosystem services they promote as well as the main uses for which the reefs are created. Impact of Artificial Reefs on the Environment and Communities presents insights on the connection between artificial reefs and the tourism industry in order to encourage the sharing of experiences and development of new innovative possibilities that create value for society. It presents the experiences, testimonies, and innovations of those who work closely with artificial reefs. Covering topics such as computational fluid dynamics, dive tourism, and Industry 4.0, this book is an essential resource for entrepreneurs, researchers, students and educators of higher education, coastal managers, government officials, leaders in tourism, engineers, and academicians.

Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

This book is open access under a CC BY-NC 2.5 license. The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.

Gray snappers were collected from four different habitats and examined for trematodes. The incidence of each trematode was calculated for each habitat during each season. Intermediate hosts of the trematodes were also collected. It was found that the habitat in which gray snappers reside is more important than their size, sex, or the season of the year in determining the nature of their trematode populations. This may be the result of the intermediate host distribution being regulated by the habitat. Seasonal changes in trematode populations result from fish movements, such as spawning migrations or movements in response to cold water. The differences between the trematode populations of large and small snappers probably are a function of their residing in different habitats and eating different organisms. The sex of gray snappers has no discernable [i.e. discernible] effect on their trematode populations. Metadena obscura sp. n. (Cryptogonimidae) was found in the pyloric caeca and intestine of Lutjanus griseus (Linnaeus). Nine species of trematodes were found in the intestine and pyloric caeca of Lutjanus griseus near Lower Matecumbe Key: Metadena globosa, M. adglobosa, M. obscura, Paracryptogonimus neoamericanus, Hamacreadium mutabile, H. gulella, Helicometrina nimia, Helicometra execta, and Stephanostomum casum.
